Instructions
Build a strong deck. Don't head for the final battles of the game without a deck full of cards of the highest caliber. Choose a single type of card with which you're most comfortable, such as Lightsworn, Dark World or Monarchs.
Use Psychic Lifetrancer, Golden Ladybug or Magical Android cards during the battles. These cards will automatically replenish your life points as you play since you will not have the opportunity to rest between battles.
Stop the clones from summoning dragons with trap cards like Divine Wrath. Fail to stop the dragon summons and your life points will take a beating.
